Question

15. Find the value of x
16. Find the value of x
17. Find the height of the tree

Answer 1

15. 7.6

16. 18.7

Explanation:

15.

`(sinA)/(a)=(sinB)/(b)\\ (sin90)/(14)=(sin33)/(x)`

sin90 × x = sin33 × 14

sin90 × x = 7.6

x = 7.6 ÷ sin90

x = 7.6

16.

`(sinA)/(a)=(sinB)/(b)\\ (sin90)/(x)=(sin180-(90+61))/(9)\\(sin90)/(x) = (sin29)/(9)\\`

sin90 × 9 = sin29 × x

9 = sin29 ×x

x= 9 ÷ sin29

x = 18.7
